Question

16. Newton established that a force never occur singly in nature.
Forces always occur in pairs as a result of mutual interaction between
two bodies According to Newton third to every action, there is equal
and opposite reaction the forces of action and reaction may appear due
to actual physical contact of two bodies or even from a distance thin
law is applicable whether the bodies are at rest or they are in motion.

Answer 1

Answer:

apple Apple Music and machine should be changed in Christmas Day of party and machine should be changed in Christmas Day of party and machine should be changed in Christmas

Answer 2

Answer

1) Why it is difficult to walk on sand than on Ice ?

• Due to Friction

2) When does the law imply in day to day life?

• When we are walking we are applying a force against the ground and instead we are able to move forward

• Friction is more on rough surfaces than smooth ones so as ice is smoot it is hard to walk there, on the other hand sand is rough which makes it that the friction is more and so easy to walk
• Not just walking is an application for Newton's second law, there are more. Recoil of a gun is also an example. When we shoot as the bullet is forced out of the gun we would experience a force backward

Newton's First Law :

☯ A body in rest continues to be in rest and a body in linear motion continues to be in linear motion untill and unless an external force is applied

Newton's Second Law

☯ The rate of change of Momentum of a body is proportional to the applied unbalanced force in the direction of force
